求教两道GWD-TN-5的逻辑

yuyinank0329

1、A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company’s warranty.The reworked jobs are invariably satisfactory.When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.



The argument above assumes which of the following?



A.！There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.

B.There is no company that successfully competes with Ace Repairs for complex repair jobs.

C.Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.

D.Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.

E.There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.

这道题完全不知所云啊，有哪位同学能帮我解释一下？感谢万分！
2. Printwell’s Ink Jet Division manufactures ink-jet printers and the ink cartridges they use.Sales of its ink-jet printers have increased.Monthly revenues from those sales, however, have not increased, because competition has forced Printwell to cut the prices of its printers.Unfortunately, Printwell has been unable to bring down the cost of manufacturing a printer.Thus, despite the increase in printer sales, the Ink Jet Division must be providing the company with much smaller than it used to.



Which of the following, if true, most seriously weakens the argument?



A.Ink-jet printers in regular use frequently need new ink cartridges, and Printwell’s printers only accept Printwell’s ink cartridges.

B.Unlike some competing companies, Printwell sells all of its printers through retailers, and these retailers’ costs account for a sizable proportion of the printers’ ultimate retail price.

C.Some printer manufacturers have been forced to reduce the sale price of their ink-jet printers even more than Printwell has.

D.In the past year, no competing manufacturer of ink-jet printers has had as great an increase in unit sales of printers as Printwell has.

E.In the past year, sales of Printwell’s ink-jet printers have increased more than sales of any other type of printer made by Printwell.

这道题选A，难道是说P的打印机不需要使用新的cartridges，所以在成本上还是有优势的吗？望牛人解答！

请牛人帮助啊

第二题是这个牌子的打印机只能使用这个牌子的墨水，所以销量不会有什么大影响。大概是这个样子的解释，晚上脑壳疼我没有仔细重看题目==

第一道题我也同求啊！  
第二道：
原文结论： 即是销量增加，但是回报会减少

A选项 因为该公司打印机经常需要换新的墨水盒，而且只能用本公司的墨水盒，
      所以打印机销量增加的同时，墨水盒的销售量也会增加（附加收入）  -->  回报会增加

如果将A取非，就是 销量增加，墨水盒也不会增加， 没有附加收入， 回报不会增加  support 原文， 所以A是正确选项

第一道我第一次做也错了，看了很多帖（我的CR不是很好……囧~）
我按照我的理解说吧：
原文的大致意思是：AR公司有大量复杂的修理要求返工。返工的工作总是让人满意的。因此，当第一遍没完全修好时，不是因为维修人员能力不行而是因为有一个a level of  focused concentration使得返工比第一遍修理更加可靠（也就是这个返工要求比第一次更加认真专心）。
那就是说，因为这个公司的repair work侧重于在返修时更认真，那么有了返修这个保障，第一次可能就没这么认真了
这里，reasoning line:  rework总是让人满意--->gap---> initial work不好不是因为能力不行，原因是返工要求比第一次更加认真专注
这里的gap是什么呢？假如intial work是学徒或者新手，而返修的是熟练工，那么initial work也会做得不好，返修后也会让人满意，那就不是专不专心的问题了。
而A选项中，前后两次work都是同一水平的人，那么你的技术摆在那里，干不干得好就取决于你认不认真了。

也不知道是不是这样的理解，欢迎讨论指正哈~~

Hi,

the passage states that the first level of repair is not of good quality but the second level of repair work is good.
it immediately comes to the conclusion that Mechanics concenteration is the reason behind the level of work.
If this has to be true or for anyother worker related argument to be true, the passage should first state / assume that the Mechanics at both levels are equally qualified and their work environment is the same.

Argument clearly says rework is not because the mechanics lack competence
that means there is an assumption that A. There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.
